Public Service Company of Oklahoma (PSO) wants to buy three new wind farms and three new solar facilities, according to a Nov. 17 filing with the Oklahoma Corporation Commission (OCC).
The American Electric Power (AEP) subsidiary said the six renewable projects combined would add 995.5 MW of capacity.
The 265 MW Lazbuddie wind farm in Parmer County, TX and the 189 MW Pixley solar farm in Barber County, KS would be completed in April 2025.
The other four renewable projects would be finished in December 2025: 135 MW Flat Ridge IV wind in Kingman & Harper Counties, KS, 153 MW Flat Ridge V wind in Harper County, KS, the 103.5 MW Chisholm Trail solar farm in Sedgwick County, KS and the 150 MW Algodon solar farm in Terry County, TX.
The company’s 2021 Integrated Resource Plan (IRP) submitted to regulators set forth PSO’s need for additional capacity beginning in 2023 for 40 MW, growing to 80 MW in 2024 and to 733 MW in 2025.
PSO determined its plan would be to acquire 4,150 MW of new renewable resources, including 1,400 MW of wind generation for each of the years 2024 and 2025; and 900 MWs of solar generation in 2024 and 450 MWs of solar generation in 2025.
The proposed additions stem from new rules from Southwest Power Pool (SPP) that require utilities to have available additional generation capacity to support reliability.
